 3.1 Shell Syntax
 ================

* Shell Operation     The basic operation of the shell.
* Quoting             How to remove the special meaning from characters.
* Comments            How to specify comments.
 
    When the shell reads input, it proceeds through a sequence of
 operations.  If the input indicates the beginning of a comment, the
 shell ignores the comment symbol (`#'), and the rest of that line.
 
    Otherwise, roughly speaking,  the shell reads its input and divides
 the input into words and operators, employing the quoting rules to
 select which meanings to assign various words and characters.
 
    The shell then parses these tokens into commands and other
 constructs, removes the special meaning of certain words or characters,
 expands others, redirects input and output as needed, executes the
 specified command, waits for the command's exit status, and makes that
 exit status available for further inspection or processing.
